Letters Patent No. 109,077, dated November 8, 1870.

IMPROVEMENT IN MACHINES FOR LAVING CHANNELS IN BOOTS AND SHOES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concer-n Be it known that I, SETH D. Taler, of Lynn, in the county of Essex and State of Massachusetts, have invented a new and improved. Channel-'laying Machine; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable' others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to improvements in machinery for the manufacture of boots and shoes, and consists in a combination with a last or former for holding the boot or shoe,of rubbing or smoothing-belts, rollers, or screens arranged to so act upon the soles of the boots or shoes as to-lay the-ridge ot' leather raised in forming the channel,in which the stitching or pegging for attaching the sole is done, back into the channel and smoothing it down.

Figure lis a front elevation of my improved machine;

Figure 2 is a sectional elevation ofthe same on the line x :v of g. 1; l

Figure 3 is a section through-the last and side view of some 0f the rubbing or laying devices which I propose to use;

4Figure 4 is a plan view of one form of rubbing deiice and the mandrel used for manipulating it; auf

.Figure 5 is a plan` view of a different form of rubbing device; also, the mandrel operating it.

Similar letters of reference indicate corresponding parts.

y Ais a last or form for holding a boot or shoe, preferably arranged in an inverted position, and attached by its' shank to a shaft, B, mounted horizontally in a frame, C, so as to osoillate freely; and, in practice, it is to be provided with a segmental gear, D, by which it may be turned back and forth b'y suit-- able gearing.

E represents a pair of mandrels or arbors, sup` ported at one end byball-and-socket or universal intconneotio1 is, with revolving tubes F, mounted on stud-pins G, radiating from the shaft H, arranged horizontally across the frame, parallel with the shaft B, and about as high or a little higher than the toprof the last A, which shaft is capable of oseillation, to allow-the arbors to swing in vertical planes t-Q any required extent.

These tubes F are to be turned by bolts from suitable driving machinery, or they may have bevel- 'gear or friction-wheels -I, connecting with suitable" bevel-wheels arranged von the shaft H, to turn independently of it, and actuated by any suitable means.

'lhe mandrels E range along the sides of the last at suitable distances therefrom, and extend beyond to the front side of the frame of the machine.

The front ends'of the mandrels have tubes K fixed on them, which have handles L at the front ends, and extend along the said mandrels about half their length, terminating, in some cases, in arms M, which project toward the last and support belt-pulleys N or rubbing-pulleys O; or the said arms, taking the form of a stud-pin, R, may support a sleeve, Q, having a spiral rubbing or brushing-thread, It, upon the exterior.

Then the belt o1rubbingpulleys N O are used, the man drels are provided with driving-pulleys S, at the inner ends of the tubes K, for driving them by means of the belts T U.

The belt T, which hooks over the smooth pulleys N, is intended to rise so much out of the groove as tol rub upon the leather and smooth d own the ridge raised in forming the channel for the stitching or pegging; but when the laying or rubbing down is to be`done by the rims of the roller O, which are serrated or roughened for the purpose, the belt will not bear on the leather, or at least so as not to prevent the roller from bearing upon it'.

The rubbing-belts may be of India rubber, leather, or any substance which will have the necessary friction, or metal chains may be used.

In case the spirally-threaded laying or rubbing device, shown in iig. 5, is to be used, the mandrel will carry a beveled friction or toothed wheel, V, in the place of the pulley S gearing with a similar wheel on the sleeve Q.

The boot'or shoe being placed on the lastA, and having a'vibratory motion imparted to it, the mandrels E or the handles L of the sleeves thereon, are taken in hand bythe operator, and held so that the laying or rubbing devices, which are set iu motion,

will act on the sole as it-vibrates back'and forth, v

to brush orrub the ridge'otf leather down into the channel. v

I propose in some cases to make the, last stationary, and arrange the-supporting shaft H for the mandrels to slide back and forth,'for causing the proper movement of the rubbing or laying devices along the sole from end to end.

l may also, as is obvious from the foregoingdescription, arrange the rubbing or laying devices, in stationary supports, and cause the last holding the shoe to traverse along the rubbing instruments while being held in contact with it.

Heretofore this operation has been done by hand at a considerablel expense of time and labor, much of which is econo'mizedbythis improved machine.
